Have you considered inpatient hospice? That's what I do, we have the same shifts as hospitals (i.e., no on call, 3 12's) and practice many clinical skills (except IV, which we rarely do). But it's not available in all areas, often you can only do in-home hospice.
Agree with pp, float nursing is probably more stressful than regular med/surg. Guess which units normally need floats? (Yes, the worst ones of course). That's why the pay it typically better.
But whatever you do, I wish you good luck. And yes, I would not stay one day beyond the contact period and not sign another one!
